Is it not plain to those who inherit the earth after its inhabitants that if We willed We could smite them for their sins and set a seal upon their hearts, so that they do not hear. 100 Such were the towns whose story We (thus) relate unto thee: There came indeed to them their messengers with clear (signs): But they would not believe what they had rejected before. Thus doth Allah seal up the hearts of those who reject faith. 101 We did not find many of them faithful to their promises, and found many of them disobedient. 102 After those We sent forth Moses with Our signs to Pharaoh and his nobles, but they dealt with Our signs unjustly. Observe, then, what happened to the mischief-makers. 103 Moses told the Pharaoh, "I am a Messengers from the Lord of the Universe. 104 so constituted that I cannot say anything about God but the truth. I have now come unto you with a clear evidence from your Sustainer: let, then, the children of Israel go with me!" 105 The Pharaoh asked Moses to show his miracles if he was telling the truth. 106 So Moses threw down his staff and suddenly it turned into a real serpent. 107 And he drew forth his hand, and lo! it was white to the beholders. 108
